The Petersköpfl is a 1,745 m AA high summit in the Zahmer Kaiser, the northern ridge of the Kaisergebirge mountain range in the Austrian state of Tyrol. To the east the Petersköpfl is linked by a ridge to the Einserkogel, to the west it is separated from the Naunspitze by a wind gap. To the south it falls steeply into the Kaisertal valley, to the north its steep rock faces tower above Ebbs. To the east there is a gently sloping plateau covered with mountain pine that forms the main ridge of the Zahmer Kaiser and runs up to the Pyramidenspitze.
